JAMES H. HERRING, OF MURPHY, TEXAS, ASSIGNOR OF ONE-HALF TO T. P.OHADDICK, OF SAME PLACE.

SHADE AND CURTAIN FIXTURE.

SPECIFICATION forming part of Letters Patent No. 486,040, dated November8, 1892.

Application filed May 14, 1892.

To all whom it may concern:

Be it known that I, JAMES H. HERRING, of Murphy, in the county of Collinand State of Texas, have invented a new and useful Shade and CurtainFixture, of which the following is a full, clear, and exact description.

The objects of this invention are to provide a simple, practical, andefficient device which will afford adjustable support for a windowshadeand also for a curtain-pole, whereby the curtain and shade may betogether lowered and permit the free entrance of light above thesescreens or the admission of air through a lowered upper sash.

To these ends my invention consists in the peculiar construction ofparts and their combination,asishereinafterdescribed and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is an inside elevation of a window with the improvements inposition thereon. Fig. 2 is an enlarged vertical section on the line 2 2in Fig. 1, broken away below. Fig. 3 is an inner end view of a detail ofconstruction, in section on the line 3 3 in Fig. 2. Fig. 4 is an endview of parts in the direction of the arrow 4 with other featuresremoved, on the line t t in Fig. 2. Fig. 5 is an end view of thebracketed casing for the features of construction shown in Figs. 3 and4, with connected parts removed. Fig. 6 is an enlarged sectional andbroken plan view of parts, on the line 6 6 in Fig. 2; and Fig. 7 is aplan view in section enlarged and broken, taken on the line 7 7 in Fig.1.

The Window-casement A may be of any preferred finish, containing sashesBand C, that are adapted for vertical sliding adjustment, the improvedwindow curtain and shade support being an attachment thereon.

There are two similar guide-strips a provided, that are securedvertically upon the inner side of the stiles of the easement A, whichstrips are laterally grooved, as shown in Fig. 6, which adapts them toretain a bracket-box b on each strip, said boxes, that are of properlength foreiiective service, having each a longitudinal groove formed inone face of a suitable depth, and on opposite side Serial No. 432,998.(No model.)

walls of said groove have tongues projected that are shaped to looselyfit within the grooves of the strips a.

Upon each bracket-box Z) there is an arm b outwardly projected, whichhave rounded grooves formed in their upper ends for the reception andretention of a curtain-pole D, that may be of any preferred style, itbeing designed to sustain pendent curtains affixed thereto by usualmeans. (Not shown.)

At opposite points in the sides of the sliding bracket-boxes b, that areinnermost when these are in position on the guide-strips a, the pintleends of the spring shade-roller c are inserted, one pintle being adaptedto interlock with the perforation of the box and the other cylindricalpintle loosely held in a mating hole in the bracket-boxit engages, sothat the spring 0' of the shade-roller will rotate said roller andelevate the shade E, when the latter is properly manipulated to effectsuch a result,there being by preference a gravity-actuated-pawlmechanism,such as is indicated in Fig. 3, employed to restrain the retation of the shade-roller at any desired point, or any otherarresting-fixture of approved form may be used in connection with theshade-roller to effect its rotary adjustment, and thus sustain the shadeE at any desired point of lowered adjustment on its own roller. A noveldevice is provided to sustain the boxes I) and permit them, with thecurtain and shade attachments, to be elevated and depressed at will,consisting, essentially, of parts that will now be described.

A bracket-plate 01 supports a journal-stud d, which is projected fromits center, said plate being in service secured near the center of thecap-piece A on the easement A, as represented in Fig. 1. Upon the stud da springcase is mounted to rotate, which case comprises a circular backplate 6, from which concentrically projects a cylindrical shell e ofless diameter, allowing an edge portion of the plate to project as aradial flange from the shell at one end of the latter. From thecenter'hub e of the spring-case spaced ribs a project, that are integralwith the hub, plate a and shell 8 serving to support the latter, andalso to hold the volute springg in proper relative position within thecase.

' cular, and its diameter is equal with that of the back plate 6, a hub6 projecting from its face that is nearest to thevolute spring 9, andribs (2 radiate therefrom, said ribs being formed integral with thecap-plate and its hub and of such a relative length as will adapt themto fit neatly within the outer portion of the shell e, the width of saidribs permitting their inner edges to loosely engage the coiled spring 9and prevent its lateral displacement when the projecting edge portion ofthe cap-plate e is in contact with the edge of the cylindrical shell 6.If found desirable, the body of the shell 6 may be formed integrallywith the cap-plate e and bear on the back plate e without impairing theefficiency of the shell.

Upon the projecting end portion of the stud d, which is squared in thebody exterior of the cap-plate 6 a locking-disk h is placed, whichlatter is apertured to [it the squared shank or stud, and hasdetent-notches it cut in its circular edge, as represented in Fig. 3,which are adapted to receive the toes of the pawls If, that are pivotedupon the outer face of the cap-plate 6 Preferably, there is acir cularflanged lid islid upon the outer squared end of the stud d, it beingperforated centrally to fit said stud, and outside of the lid a washer tis placed on the stud end, a transverse key t that passes through a holein the stud-body serving to retain all parts in their relative position.

The loosely-mounted back plate 6 and cap plate e are held in lockedengagement with each other, preferably by projecting the postg' into aperforation in a rib 6 as shown in Fig. 2 by dotted lines. On the upperpart of the casement-stiles at proper points two similar small groovedpulleys m are sustained by a screw-bolt m for each pulley, the latterbeing spaced from the casement-face by a sleeve-block m strung upon eachscrewbolt and held by it between the pulley and casement, as indicatedin Fig. 7.

Upon the cylindrical shell 6 two flexible strands n n are wrappedoppositely on the shellthat is, one end of each strand is attached tothe shell, one at the top and the other at the bottom of the shellandafter a proper number of coils have been located on the shell thestrands are extended in opposite directions toward the stiles of thewindowcasement, resting on the grooved pulleys m, and thence dependingsufticiently to have their remaining ends attached to the upper ends ofthe bracket-boxes b. The strands n a are by preference made of :twistedwire formed into a cord, thereby insuringstrength without objectionablethickness.

On the lower end of each of the bracketboxes I) an adjusting-cord 0 isattached by one end, so as to hang pendent, and of alength that willafford a convenient means to adjust the height of the curtain-roller andwindow shade.

In use the volute spring Q will be wrapped closer when the bracket-boxesb are drawn down and retained from uncoiling by a looking engagement ofone of the pawls 72. with a detent-notch in the disk h, thus storingenergy that will be sufficient to elevate the boxes I) and their load iteitherot' the cords 0 is suddenly jerked down and'then released,

which will dislodge the pawl from its locked,

contact with the notched disk and permit the spring to uncoil until itsrotary motion is checked by a pull on one of the cords 0, that willallow the pawl to again fall into a notch.

It will be seen that by the construction of parts hereinbeforedescribed. the sash of the window may be lowered from above, asindicated in Fig. 1, and both the window-shade E and curtains on thepole D similarly adjusted to depress them any desired distance from thetop of the easement A, thus affording free access for light and air; orthe shade and curtains may be lowered to admit light from above when theupper sash of the window is closed, the normal position of the screeningdevices being quickly resumed by a proper manipulatlon of the pendentcords 0, as before explained. I

Having thus fully described my invention, I claim as new and desire tosecure byLetters Patent A supporting and retracting device for windowshades and curtain poles, comprising two vertically-slidingbracket-boxes on strips fixed to the stiles of the window-casement and aspring-actuated retracting device comprising a bracket-plate on thecap-piece of the casement, a stud projecting from the bracket-plate, acylindrical shell rotatable on the stud, a rotatable cap-plate on thestud and connected to the shell, a volute spring on the stud between thecap-plate and a back plate of the shell, having one end fast to theshell and the other end secured to the stud, a locking'disk fast on thestud outside of the cap-plate, pawls on the cap-plate adapted to lockwith the disk, two strands wrapped on the shell and secured by an end ofeach thereon and thence extended laterally in opposite directions overpulleys on the windowstiles and downwardly from the pulleys to aconnection with the bracket-boxes, and pulleys that support the strandson the easement, substantially as described.
